1: Table of Contents | Geometry Basics - 2 - 3 Angles and Measure - 4 -5 Angle and Segment Bisectors - 5-6 Comp.,Supp, and Vertical Angles - 7-8 Parallel lines and Transversal angles - 9-10 | Perpendicular Lines - 11 -12 Triangles - 13-14 Pythagorean Theorem 15-16 Congruent Triangles - 17-18 Polygons - 19-20
2: Pattern - A type of theme of recurring events or objects, sometimes referred as a element of a set | Distance - is between a and b and is written as AB.
3: Length - AB is also called the length of lines AB | This Is a real world example of a Pattern. It is the painting on the wall. | This is the length of a triangle.
4: Angle - Consist of two rays that have the same endpoint. | Here is an example of an angle. This angle is a right angle. | This is a real life example of an angle. The foundation of this house contains many different kinds of angles.
5: Angles and Their Measure - Angles are classified as a acute right obtuse or a Straight angle | The one on the left is an acute angle, and the one on the left is a obtuse angle.
6: Segment Bisector - Is a segment, ray, line, or plane that intersects at its midpoint. | Here is an example of a segment bisector.
7: Angle Bisector -Is a ray that divides an angle into two angles that are congruent | This picture is an example of Angle bisector. | This is a real life example of an Angle bisector. The wings of the hang glider represents as the angle
8: Complementary Angles - Two angles Are Complementary angles if the sum of their measures is 90 degrees. | This is a complementary angle and you can see how the sum is 90. | This folded uppiece of paper is an example of a complementary angle.
9: Vertical Angles - each of the pairs of opposite angles made by two intersecting lines. | Supplementary Angles - Two angles are supplementary angles if the sum of their measures is 180 degrees. | In this picture, you can see how the lines intersect. | In this picture above you can see how the sum of the angle is 180
10: Parallel Lines - Two lines are parallel lines when they lie on the same plane and do not intersect. | You can see how line A is parallel to line B | These railroad tracks are an example of parallel lines.
11: Transversal - Is a line that intersects two or more coplanar lines at different points. | In this picture, you can see how the transversal line intersects through line A and B
12: Perpendicular Lines - Two lines are Perpendicular if they intersect to form a right angle. | In this picture, you can see the example of a perpendicular line.
13: In this real world example, the cracks in the tiles are perpendicular
14: Triangle - Is a figure formed by three segments joining noncollinear points. Here is a picture of a triangle | This sign is a world example of a triangle.
15: Isosceles Triangle - Has at least 2 congruent sides. | Scalene Triangle - Doesn't have any congruent sides. | Equilateral Triangle - Has 3 congruent sides.
16: Pythagorean Theorem - A theorem attributed to Pythagoras that the square of the hypotenuse of a right triangle is equal to the sum of the squares of the other two sides | The picture on the left is the example, and the one on the bottom is the real life example.
17: Distance Formula - The Pythagorean theorem can be used to develop the distance formula which gives the distance between two points in a coordinate plane
18: Congruent Triangles - In geometry, two figures are congruent if they have the same shape and size.
19: You can prove they are congruent by making sure they have the same angle and side. | These sandwhiches are real life examples because they are cut the same way.
20: Polygon - Is a plane figure that is formed. | Rhombus - A parallelogram with four congruent sides. | Parallelogram - A four-sided plane rectilinear figure with opposite sides parallel.
21: Rectangle - A parallelogram with four right angles. | Square - A parallelogram with four congruent sides and angles | These picture are example of different kinds of polygons and parallelogram.
